Power line supply luminaire in many street lighting application utilizes underground distribution routing electric wires (wire run).These underground power lines cablings are for carrying the good candidate of the PLC signal of device controlling luminaire and associating with luminaire.The wiring of these underground power lines is special or is primarily devoted to, to lamp energization, without suffering many destructive insidents that side occurs on the ground, such as, relate to the physics disaster of structure, some Severe weather events etc..This organizes into groups transmission and/or reception communication by the one or more access points from power line to indivedual luminaires or luminaire, provides the chance of cost-effective dual utilization installation wiring.PLC technology can provide communication on distribution network (it has those networks that known and slowly varying topology, for example, street lighting are installed).In this kind of network, communication enineer knows the position of indivedual luminaire, and the prolongation and deletion to the part connected up is anticipated and known.Power line section in street lighting network is also relatively simple, and this enables the communication protocol span with street lighting network scaled to be developed.
The useful communication bandwidth of power line is the function of the many parameters comprising noise.According to the ieee standard 1901 annex F in the broadband on power line network, power line passage suffers four noise likes.They comprise hot ambient noise (it is that gaussian sum is coloured), cycle and non-periodic pulse noise, AM narrow-band noise and the noise of other users from power line communication medium.For being exclusively used in the power line providing power for street lamp, it is contemplated that rear two noise likes will be minimum.Other factors of the useful bandwidth that communicates affecting power line comprise network topology, impedance mismatching, ground connection practice and can cause reflection and phase place change and other physical characteristics of frequency selective attenuation.Also can there is the interference that or initial failure intrasystem aging by underground distribution is generated.
Considering and in the electric line communication system of planning use underground power lines cabling, it is contemplated that three aspects to the underground power distribution of street lighting systems.First, long underground power lines cabling can present electric capacity, and it increases the signal of conduction on power line and, in the decay of higher frequency, thus reduces the signal to noise ratio in these higher frequencies.
Secondly, long underground power lines cabling can sponsor (host) standing electromagnetic wave.These ripples also can increase the apparent attenuation of the power line with the frequency conducted signal corresponding with standing wave frequency.
3rd, electric-power wire communication signal may must transmit across transformer.This is partly due to the needs effectively regulated of the power met for being supplied to Traditional Streets lighting mains, and rule is at least two reasons.First, the electric current to lamp supply should be at its rated value, in order to makes lamp radiate its light with full brightness.Secondly, even more than the overcurrent being forced across lamp of lamp certain percentage specified can be by the biggest for the service life reduction in lamp life-span percentage, sometime up to 25%.In order to realize strictly regulating required by the power supplied to lighting mains, Lighting Design personnel can use Constant-Current Transformer.These transformers generally use moving coil to provide constant current.
It addition, electric-power wire communication signal can be changed when transformer transmits at them.This results from transformer and introduces the nonlinear phase shift in the broadband signal of transformer transmission via inductive.
Suitable electric line communication system can be based on amendment geometry harmonic modulation (GHM), such as United States Patent (USP) No. 5844949 and United States Patent (USP) No. 6424250 instructed, the two patent is combined by quoting.GHM is categorized as spread-spectrum modulation, because the information transmitted is by extending than by the bandwidth of the wide many required by inromation bandwidth, and it forms the physical layer (PHY) of luminaire lighting mains.Other modulation technique, such as OFDM are imagined in this application.Ofdm signal presents big papr or high crest factor, and it requires that OFDM transmitter has than the high-resolution digital to analog converter of the corresponding DAC (DAC) used in GHM conveyer.About the receiver in OFDM and GHM receiver, same is genuine.The converter requiring higher resolution trends towards increasing assembly cost.Correspondingly, although imagine other modulation techniques, but in embodiment described herein, discuss GHM.
Geometry harmonic modulation (GHM) is in a communications system for airwave communication, and entitled " Geometric Harmonic Modulation (GHM) for Combined issued on May 21st, 1996 Analog/Digital Transmissions " United States Patent (USP) No. 5519725 described in.Signaling energy is assigned to lobe or signal sound (tone) increasing the evenly spaced different frequency of multiple with the geometry of fundamental frequency by GHM.GHM signaling waveform is real extension spectrum signal, because signal bandwidth, greatly exceeding to the bandwidth of highest frequency signal sound from low-limit frequency signal sound and transmit transmitted inromation bandwidth by GHM.
United States Patent (USP) No. 5844949 that on December 1st, 1998 is issued is instructed, and by suitably modified GHM signaling waveform, waveform greatly avoids the spectral property of the synchronization noise environment of experience on many power line networks by presenting to fit entirely into.This is through more typically checking that GHM and power line noise are carried out.Determine that the lobe of modulation GHM signal should be positioned on the frequency spectrum interweaved with power line noise.Owing to power line noise can have a large amount of interference at fundamental oscillation frequency, 60 Hz of the U.S. and overtone (overtone) multiple at fundamental frequency, so signal should not reside in these frequency zones.By modulated signal to be positioned between interference lobe by the great majority of its spectrum energy, signal can be used for certain power line communications applications, and this depends on information capacity, the diversity of user, circuit coupling response and the consideration of communication channel characteristics.By correctly selecting frequency, United States Patent (USP) No. 5844949 issued such as on December 1st, 1998 is instructed, and signal structure can interweave with harmonious wave power line noise, and this realizes being referred to as amendment geometry harmonic modulation.
Amendment geometry harmonic modulation signal can strengthen through pre-before being placed on power line in another embodiment.Pre-enhancing comprises pre-boster and is applied to frequency dependent amplitude mask revise geometry harmonic modulation signal, in order to adjust frequency so that it is by receiving in institute's reconnaissance closer to equal energy in each with received signal lobe.The impact of the severe frequency correlatoin fading channel that this technology meets with in neutralisation signals is transmitted is effective.
Amendment GHM forms the PHY layer of plc communication.Medium education (MAC) layer can include this kind of function such as error detection, error correction, encryption and certification and repeat requests.Higher level communication protocol can include that such as collision detection, conflict avoidance, Carrier Sense Multiple access and time division multiple acess transmit the function controlled.
